Selena Gomez Performs in Body-Hugging Costume

Selena Gomez took to the stage at her concert in Puerto Rico wearing a bold purple outfit with a plunging neckline and leotard-like bottoms, which showed off her long legs and fit physique.

The 19-year-old pop star displayed her curvaceous body during the opening night of her South American tour, and took to Facebook in anticipation of the performance. "Puerto Rico -- 4 hours till show time, so excited to be back such a fun place to kick off my South American Tour, it's like my second home. Love you all."
